Abstract

The drive belt (15) rotates a pulley (10) in one direction which rotates a crown (6) attached to it in the same direction. The crown spins the pinion (4) causing a second crown (7) to spin in the opposite direction. The radial thrust on the pinion is taken by the roller bearing (16). The crown (7) is fixed to the central hub (3) mounted on a fixed axis (1) and the central hub (3) is also fixed to the central support and spindle (11) of the rotating drum (13) of the shutter (14), so that the shutter moves in the same direction as the central hub (3) but opposed to the command ribbon (15).
